Description

Technical Field

[0001] The invention belongs to the technical field of temperature control and regulation, and in particular is a temperature automatic control and regulation system suitable for a long rod hot shear furnace. Background Art

[0002] The long rod heating furnace is divided into a single long rod heating hot shear furnace (single rod hot shear furnace for short) and a multi-long rod heating hot shear furnace (multi-rod hot shear furnace for short). The long rod hot shear furnace has a reasonable structure, a sealed furnace body, good heat preservation, and high thermal efficiency. During the use of the long rod hot shear furnace, the length of the aluminum rod can be adjusted at any time, which is convenient for production scheduling. And because it uses aluminum rods for cutting, it avoids the waste of raw materials in the old furnace that saws off the aluminum rods.

[0003] When the long-bar hot shear furnace is currently used for processing, different products require different processing temperatures. During actual processing, the working temperature of the long-bar hot shear furnace needs to be manually adjusted through the control panel. The manual temperature adjustment method is inefficient and inaccurate.

[0004] Therefore, we propose a temperature automatic control and regulation system suitable for long rod hot shear furnace. Summary of the invention

[0010] The data acquisition module is used to collect the sealing data of the long rod hot shear furnace corresponding to the workpiece to be processed, and the sealing data is sent to the intelligent test module via the server; the storage module is also used to store the test qualified data of the long rod hot shear furnace; the intelligent test module is used to test the sealing condition of the long rod hot shear furnace corresponding to the workpiece to be processed, and the test generates a normal test signal or an abnormal test signal and feeds it back to the server. If a normal test signal is generated, no operation is performed. If a test abnormal signal is generated, it is sent to the user terminal, and the user terminal is used to view the long rod hot shear furnace;

[0011] After the test is completed, the data acquisition module is also used to collect the real-time temperature value of the workpiece to be processed when the long rod hot shear furnace is processing the workpiece, and the real-time temperature value is sent to the temperature analysis module via the server; the temperature analysis module is used to analyze the temperature conditions of the workpiece to be processed when the long rod hot shear furnace is processing the workpiece, and the analysis generates a temperature increase abnormal signal or a temperature drop abnormal signal and feeds it back to the server, and the server sends the temperature increase abnormal signal or the temperature drop abnormal signal to the intelligent control module; the intelligent control module is used to control the processing temperature of the workpiece to be processed corresponding to the long rod hot shear furnace according to the temperature increase abnormal signal or the temperature drop abnormal signal.

[0012] Furthermore, the analysis process of the product analysis module is as follows:

[0013] Obtaining the workpiece number of the workpiece to be processed input by the user terminal;

[0014] Then obtain different product numbers stored in the storage module;

[0015] Use Chinese word segmentation technology to compare the workpiece number with the product number one by one;

[0016] If the workpiece number matches any product number, the processing temperature corresponding to the product number is calibrated as the processing temperature of the workpiece to be processed;

[0017] If the workpiece number does not match any of the product numbers, a match exception signal is generated.

[0018] Furthermore, the sealing data is the number of tests of the long rod hot shear furnace, the test duration of each test, and the test furnace pressure value;

[0019] The test qualified data includes the pressure stabilization time of the long rod hot shear furnace corresponding to different furnace pressure value ranges, as well as the preset qualified rate of the long rod hot shear furnace.

[0020] Furthermore, the testing process of the intelligent testing module is as follows:

[0021] Set the test furnace pressure value of the long-bar hot shear furnace, and then obtain the test furnace pressure value of the long-bar hot shear furnace corresponding to the workpiece to be processed at different time points;

[0022] If the test furnace pressure values ​​corresponding to all time points are equal, the corresponding pressure stabilization time of the long rod hot shear furnace is obtained according to the furnace pressure value interval to which the test furnace pressure value belongs;

[0023] If the test time corresponding to the test furnace pressure value is greater than or equal to the voltage stabilization time, the test result is recorded as a qualified test.

[0024] Furthermore, the testing process of the intelligent testing module also includes:

[0025] If the corresponding test furnace pressure values ​​at different time points are not equal, then the time point is recorded as an abnormal time point, and the time from the previous time point to the abnormal time point and the time from the abnormal time point to the next time point are eliminated to obtain the test time of the long rod hot shear furnace after elimination. If the test time of the long rod hot shear furnace after elimination is greater than or equal to the voltage stabilization time, then the test result is recorded as a qualified test. If the test time of the long rod hot shear furnace after elimination is less than the voltage stabilization time, then the test result is recorded as an unqualified test.

[0026] Gradually increase the test furnace pressure value of the long rod hot shear furnace, and perform the test according to the above steps, and record the test results of each test;

[0027] The number of qualified tests of the long-bar hot shear furnace is counted and recorded as the qualified test number, and the qualified test number is compared with the test number to obtain the test qualified rate of the long-bar hot shear furnace;

[0028] If the test pass rate is greater than or equal to the preset pass rate, a test normal signal is generated; if the test pass rate is less than the preset pass rate, a test abnormal signal is generated.

[0029] Furthermore, the analysis process of the temperature analysis module is as follows:

[0031] If the real-time temperature value at the current time point is equal to the processing temperature value, the real-time temperature value at the previous time point is obtained; when the real-time temperature value at the current time point is equal to the real-time temperature value at the previous time point, the time from the previous time point to the current time point is not recorded, when the real-time temperature value at the current time point is greater than the real-time temperature value at the previous time point, the time from the previous time point to the current time point is recorded as the temperature increase removal time segment, when the real-time temperature value at the current time point is less than the real-time temperature value at the previous time point, the time from the previous time point to the current time point is recorded as the temperature decrease removal time segment.

[0032] Furthermore, the analysis process of the temperature analysis module also includes:

[0033] If the real-time temperature value at the current time point is not equal to the processing temperature value, then obtain the real-time temperature value at the previous time point;

[0036] Furthermore, the analysis process of the temperature analysis module also includes:

[0037] The duration of the cooling elimination time segment and the heating elimination time segment are counted separately;

[0038] If the duration of the cooling removal time segment exceeds the preset abnormal duration, a cooling abnormal signal is generated. If the duration of the cooling removal time segment does not exceed the preset abnormal duration, the duration of the cooling removal time segment is accumulated. If the total duration of the cooling removal time segment after accumulation exceeds the preset abnormal duration, a cooling abnormal signal is also generated. Otherwise, no operation is performed.

[0039] If the duration of the temperature increase exclusion time segment exceeds the preset abnormal time segment, a temperature increase abnormal signal is generated; if the duration of the temperature increase exclusion time segment does not exceed the preset abnormal time segment, the duration of the temperature increase exclusion time segment is accumulated; if the total accumulated duration of the temperature increase exclusion time segment exceeds the preset abnormal time segment, a temperature increase abnormal signal is also generated; otherwise, no operation is performed.

[0040] Furthermore, neither the current time point nor the previous time point is the starting time point when the temperature value in the long rod hot shear furnace reaches the processing temperature value.

[0041] Furthermore, the control process of the intelligent control module is:

[0042] If a temperature increase abnormal signal is received, the temperature is increased according to the temperature increase value between the real-time temperature value and the processing temperature value;

[0043] If a temperature drop abnormal signal is received, the temperature is dropped according to the temperature drop value between the real-time temperature value and the processing temperature value.

[0044] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0045] The present invention utilizes a user terminal to input a workpiece number of a workpiece to be processed, analyzes the product conditions of the workpiece to be processed in a long rod hot shear furnace according to the workpiece number, obtains the processing temperature of the workpiece to be processed or generates a matching abnormal signal through analysis, and inputs and sets the processing temperature of the workpiece to be processed if the analysis generates a matching abnormal signal, and performs processing on the workpiece to be processed according to the processing temperature.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The user terminal is used to input the workpiece number of the workpiece to be processed and send the workpiece number to the server, and the server sends the workpiece number to the product analysis module;

[0053] The storage module is used to store the processing temperature values ​​of the processed parts corresponding to different product numbers. In this embodiment, the storage module is data-connected with the product analysis module;

[0054] The product analysis module is used to analyze the product conditions of the workpieces to be processed in the long bar hot shear furnace. The specific analysis process is as follows:

[0055] Obtaining the workpiece number of the workpiece to be processed input by the user terminal;

[0056] Then obtain different product numbers stored in the storage module;

[0057] Use Chinese word segmentation technology to compare the workpiece number with the product number one by one;

[0058] If the workpiece number matches any product number, the processing temperature corresponding to the product number is calibrated as the processing temperature of the workpiece to be processed;

[0059] If the workpiece number does not match any product number, a match exception signal is generated;

[0060] The product analysis module feeds back the processing temperature of the workpiece to be processed or the generated matching abnormality signal to the server. If the server receives the matching abnormality signal, the matching abnormality signal is sent to the user terminal. The user terminal is used to input and set the processing temperature of the workpiece to be processed after receiving the matching abnormality signal. If the server receives the processing temperature of the workpiece to be processed, the processing temperature of the workpiece to be processed is sent to the execution component. The execution component is used to process the workpiece to be processed according to the processing temperature.

[0061] In practice, the actuator is a control device equipped on the long rod hot shear furnace, which can realize the control of the temperature value and working time of the long rod hot shear furnace when it is working.

[0062] In this embodiment, the data acquisition module is used to collect the sealing data of the long rod hot shear furnace corresponding to the workpiece to be processed, and send the sealing data to the server, and the server sends the sealing data to the intelligent testing module;

[0063] It should be specifically stated that the sealing data is the number of tests of the long rod hot shear furnace, the test duration and the test furnace pressure value of each test. In practice, the test furnace pressure value can be gradually increased until the test furnace pressure value reaches the upper limit of the pressure of the long rod hot shear furnace. At the same time, multiple time points are set during each test duration, and the test furnace pressure value is collected at the time point. The test duration starts when the long rod hot shear furnace reaches the corresponding test furnace pressure value, and the test ends when the test duration is reached;

[0064] The storage module is also used to store the test qualified data of the long rod hot shear furnace, and the test qualified module is data-connected with the intelligent test module, wherein the test qualified data is the voltage stabilization time corresponding to the long rod hot shear furnace in different furnace pressure value intervals, and the preset qualified rate of the long rod hot shear furnace;

[0065] The intelligent testing module is used to test the sealing condition of the long bar hot shear furnace corresponding to the workpiece to be processed. The specific testing process is as follows:

[0066] Set the test furnace pressure value of the long-bar hot shear furnace, and then obtain the test furnace pressure value of the long-bar hot shear furnace corresponding to the workpiece to be processed at different time points;

[0067] If the test furnace pressure values ​​corresponding to all time points are equal, the corresponding pressure stabilization time of the long rod hot shear furnace is obtained according to the furnace pressure value interval to which the test furnace pressure value belongs;

[0068] If the test duration corresponding to the test furnace pressure value is greater than or equal to the voltage stabilization time, the test result is recorded as a qualified test; if the test duration corresponding to the test furnace pressure value is less than the voltage stabilization time, the test result is recorded as an unqualified test;

[0069] If the corresponding test furnace pressure values ​​at different time points are not equal, then the time point is recorded as an abnormal time point, and the time from the previous time point to the abnormal time point and the time from the abnormal time point to the next time point are eliminated to obtain the test time of the long rod hot shear furnace after elimination. If the test time of the long rod hot shear furnace after elimination is greater than or equal to the voltage stabilization time, then the test result is recorded as a qualified test. If the test time of the long rod hot shear furnace after elimination is less than the voltage stabilization time, then the test result is recorded as an unqualified test.

[0070] Gradually increase the test furnace pressure value of the long rod hot shear furnace, and perform the test according to the above steps, and record the test results of each test;

[0071] The number of qualified tests of the long-bar hot shear furnace is counted and recorded as the qualified test number, and the qualified test number is compared with the test number to obtain the test qualified rate of the long-bar hot shear furnace;

[0072] If the test pass rate is greater than or equal to the preset pass rate, a test normal signal is generated; if the test pass rate is less than the preset pass rate, a test abnormal signal is generated;

[0073] The intelligent test module feeds back a normal test signal or an abnormal test signal to the server. If the server receives a normal test signal, it does not perform any operation. If the server receives an abnormal test signal, it sends it to the user terminal. The user terminal is used to check the long rod hot shear furnace after receiving the abnormal test signal.

[0074] After the test is completed, when the long rod hot shear furnace processes the workpiece to be processed, the data acquisition module is also used to collect the real-time temperature value of the long rod hot shear furnace when processing the workpiece to be processed, and send the real-time temperature value to the server, and the server sends the real-time temperature value to the temperature analysis module;

[0075] The temperature analysis module is used to analyze the temperature of the workpiece when the long rod hot shear furnace is processing the workpiece. The specific analysis process is as follows:

[0076] Obtain the real-time temperature value of the workpiece being processed in the long-bar hot shear furnace, and compare the real-time temperature value with the processing temperature value;

[0077] A. If the real-time temperature value at the current time point is equal to the processing temperature value, the real-time temperature value at the previous time point is obtained; when the real-time temperature value at the current time point is equal to the real-time temperature value at the previous time point, the duration from the previous time point to the current time point is not recorded; when the real-time temperature value at the current time point is greater than the real-time temperature value at the previous time point, the duration from the previous time point to the current time point is recorded as the temperature increase removal duration segment; when the real-time temperature value at the current time point is less than the real-time temperature value at the previous time point, the duration from the previous time point to the current time point is recorded as the temperature decrease removal duration segment;

[0078] Among them, the current time point and the previous time point are not the starting time points when the temperature value in the long-bar hot shear furnace reaches the processing temperature value;

[0079] B. If the real-time temperature value at the current time point is not equal to the processing temperature value, the real-time temperature value at the previous time point is obtained; wherein, neither the current time point nor the previous time point is the starting time point when the temperature value in the long bar hot shear furnace reaches the processing temperature value;

[0080] B1. When the real-time temperature at the previous time point is equal to the processing temperature value: when the real-time temperature value at the current time point is greater than the processing temperature value, the time from the previous time point to the current time point is recorded as the temperature increase removal time segment; when the real-time temperature value at the current time point is less than the processing temperature value, the time from the previous time point to the current time point is recorded as the temperature decrease removal time segment;

[0081] B2. The real-time temperature at the previous time point is not equal to the processing temperature value: when the real-time temperature value at the current time point is greater than the real-time temperature value at the previous time point, the time from the previous time point to the current time point is recorded as the temperature increase removal time segment; when the real-time temperature value at the current time point is less than the real-time temperature value at the previous time point, the time from the previous time point to the current time point is recorded as the temperature decrease removal time segment;

[0082] The duration of the cooling elimination time segment and the heating elimination time segment are counted separately;

[0083] If the duration of the cooling removal time segment exceeds the preset abnormal duration, a cooling abnormal signal is generated. If the duration of the cooling removal time segment does not exceed the preset abnormal duration, the duration of the cooling removal time segment is accumulated. If the total duration of the cooling removal time segment after accumulation exceeds the preset abnormal duration, a cooling abnormal signal is also generated. Otherwise, no operation is performed.

[0084] If the duration of the temperature increase rejection time segment exceeds the preset abnormal time segment, a temperature increase abnormal signal is generated. If the duration of the temperature increase rejection time segment does not exceed the preset abnormal time segment, the duration of the temperature increase rejection time segment is accumulated. If the total duration of the temperature increase rejection time segment after accumulation exceeds the preset abnormal time segment, a temperature increase abnormal signal is also generated. Otherwise, no operation is performed.

[0085] The intelligent analysis module feeds back the abnormal temperature increase signal or the abnormal temperature drop signal to the server, and the server sends the abnormal temperature increase signal or the abnormal temperature drop signal to the intelligent control module; the intelligent control module is used to control the processing temperature of the long rod hot shear furnace corresponding to the workpiece to be processed according to the abnormal temperature increase signal or the abnormal temperature drop signal;

[0086] In practice, after receiving a temperature increase abnormal signal, the temperature is increased according to the temperature increase value of the real-time temperature value and the processing temperature value, and after receiving a temperature decrease abnormal signal, the temperature is decreased according to the temperature decrease value of the real-time temperature value and the processing temperature value;

[0087] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
